BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention belongs to the area of low-temperature residual heat utilization.

2. Description of Related Arts

Under the premise that the heat pump can promote the residual heat temperature to the needed level of the user, adopting the absorption heat pump (AHP) technology to develop residual heat can bring a better energy conservation, environmental protection and economic interest. Promoting the heating temperature of the heat pump, using the lower temperature of the waste heat resources and improving the utilization rate of the waste heat resources are the main directions of people's efforts.

To get a higher heating temperature and performance index of the AHP, people explored several different effects and different stages units at first and different heat pump processes are compounded by many ways such as adding the heating-side, increasing the process of heating and so on. Then they got more meticulous effects and stages which are corresponding to the corresponding performance index. However, these single-effect or single-stage units own some deficiencies that each single-effect or single-stage units has the right work parameter and performance index just in a particular situation. For example, a single two level units has a high heating temperature while its performance index is low.

Seeing from the internal process of the units, the key to improve the heating temperature of the second-type absorption heat pump is to enhance the export solution concentration of the absorber. That means to promote the export solution concentration of the generator. It can improve the heating temperature of the corresponding units by using the recuperative principle to the generation-absorption process of the solution, establishing the recuperative generation-absorption system and compounding with different effects and different stages units. At the same time, adopting the way of recuperative heat can realize two-terminal heating or multiterminal heating of the second-type absorption heat pump which is useful for improving the performance index of the units.

SUMMARY OF THE PRESENT INVENTION

An main object of the present invention is to provide a recuperative generation-absorption system of solution tandem cycle and a recuperative generation-absorption system of solution independent loop at first, then add some components in the two recuperative generation-absorption systems to gain the second-type absorption heat pump with a higher heating temperature which can be called the recuperative second-type absorption heat pump too. The specific contents of the present invention are described as follows.

1. One of the recuperative generation-absorption systems in this invention is the solution tandem cycle recuperative generation-absorption system which can be mainly formed by the generator, the first absorber, the second absorber, the first solution heat exchanger, the second solution heat exchanger, the steam bleeding chamber, the first solution pump, the second solution pump or plus the third solution pump.

The concentrated solution pipe of generator passes through the first solution pump, the first solution heat exchanger and the first absorber and then connects the steam bleeding chamber. The concentrated solution pipe of the steam bleeding chamber passes through the second solution pump, the second solution heat exchanger and then connects the second absorber. The dilute solution pipe of the second absorber passes through the second solution heat exchanger, the third solution pump if the system has it and then connects the first absorber. The dilute solution pipe of the first absorber passes through the first solution heat exchanger and then connects generator.

Generator has the pipe of residual heat medium or the pipe of thermal driving medium and the channel of refrigerant vapor which separately connect external. The first absorber has the pipe of heated medium and the channel of refrigerant vapor which separately connect external. The second absorber has the channel of refrigerant vapor and the channel of heated medium which separately connect external. The steam bleeding chamber has the channel of refrigerant vapor which connects external.

The dilute solution of generator is heated by the residual heat medium or the thermal driving medium and releases refrigerant vapor. The concentrated solution of generator flows through the first solution pump, the first solution heat exchanger, the first absorber in which it absorbs heat and a part of it is vaporization and then enters the steam bleeding chamber which releases refrigerant vapor. The concentrated solution pipe of the steam bleeding chamber flows through the second solution pump, the second solution heat exchanger and then enters the second absorber in which it absorbs the refrigerant vapor coming from outside the system and releases heat to the heated medium at the same time.

The dilute solution of the second absorber flows through the second solution heat exchanger, the third solution pump if the system has it and then enters the first absorber in which it absorbs the refrigerant vapor coming from outside the system and heats up the solution which flows through the first absorber and meets the heat demand of heated medium. The dilute solution of the first absorber flows through the first solution heat exchanger and then flows back to generator in which it releases refrigerant vapor. Then we gain the recuperative generation-absorption system of solution tandem cycle.

When the first absorber haven't the pipe of heated medium connected external, the heat which is released by absorbing the refrigerant vapor in the first absorber is used to heat the solution which flows through the first absorber.

2. One or two of the recuperative generation-absorption systems in this invention is solution independent loop recuperative generation-absorption system which can be mainly formed by generator, the first absorber, the second absorber, the first solution heat exchanger, the second solution heat exchanger, the steam bleeding chamber, the first solution pump, the second solution pump.

The concentrated solution pipe of generator passes through the first solution pump, the first solution heat exchanger and then connects the first absorber. The dilute solution pipe of the first absorber passes through the first solution heat exchanger and then connects generator. The dilute solution pipe of the second absorber passes through the second solution heat exchanger, the first absorber and then connects the steam bleeding chamber. The concentrated solution pipe of the steam bleeding chamber passes through the second solution pump, the second solution heat exchanger and then connects the second absorber.

Generator has the pipe of residual heat medium or the pipe of thermal driving medium and the channel of refrigerant vapor which separately connect external. The first absorber has the pipe of heated medium and the channel of refrigerant vapor which separately connect external. The second absorber has the channel of refrigerant vapor and the channel of heated medium which separately connect external. The steam bleeding chamber has the channel of refrigerant vapor which connects external.

The dilute solution of generator is heated by the residual heat medium or the thermal driving medium and releases refrigerant vapor at the same time. The concentrated solution of generator flows through the first solution pump, the first solution heat exchanger and then enters the first absorber in which it absorbs the refrigerant vapor coming from outside the system and heats up the solution which flows through the first absorber and meets the heat demand of heated medium. The dilute solution of the first absorber flows through the first solution heat exchanger and then flows back to generator. The solution which flows through the first absorber absorbs heat and a part of it is vaporization and then enters the steam bleeding chamber which releases refrigerant vapor. The concentrated solution pipe of the steam bleeding chamber flows through the second solution pump, the second solution heat exchanger and then enters the second absorber in which it absorbs the refrigerant vapor coming from outside the system and releases heat to the heated medium at the same time. The dilute solution of the second absorber flows through the second solution heat exchanger, the first absorber and then enters the steam bleeding chamber. Then we gain the recuperative generation-absorption system with solution independent loop.

When the first absorber haven't the pipe of heated medium connected external, the heat which is released by absorbing the refrigerant vapor in the first absorber is used to heat the solution which flows through the first absorber.

In a specific and complete second-type absorption unit, the refrigerant vapor and solution all belong to the working medium of unit. In the above generation-absorption system, the first absorber absorbs the refrigerant vapor of outside the system and releases heat to the solution which flows through the first absorber. Then the solution which enters the first absorber absorbs refrigerant vapor and releases heat. The heat is released by working medium. That the solution which flows through the first absorber absorbs heat can be regarded as absorption heat by working medium. This process is called recuperative heat in terms. In the cycle, working medium releases heat in a process which can be used to meet the absorption of heat by working medium in another process. The generation-absorption systems in this invention are recuperative generation-absorption systems.

According to the needed terminal temperature of heated medium, we need to adjust the amount of vapor released by the solution in the steam bleeding chamber. It depends on the quantity of heating load absorbed by the solution which flows through the first absorber. The less the heating load is, the less the amount of refrigerant vapor which separated from the solution in the steam bleeding chamber is. At the same time, the concentration of solution which enters the second absorber increases less and the terminal temperature of heated medium is promoted much less too. What's more, the corresponding performance index of the second absorber is more close to the first absorber's on the condition that the quantity of refrigerant vapor absorbed by the first absorber and the second absorber is consistent. In a certain range, the second-type absorption heat pump which is combined with this invention can achieve high-temperature heating with a higher performance index.

Meanwhile, the third solution pump 9 is used to overcome the resistance when the solution flows through the heat exchanger and the pipeline. But the solution pump will save when the altitude (gravity) difference exists and can be used. The third solution pump 9 can save too when the pressure of the second absorber 3 is higher than the pressure of the first absorber 2.

Secondly, the solution heat exchanger can act as the throttle which is used for throttling step-down.

So do single stage parallel triple effect.

Fifthly, the tandem cycle double-effect in the single stage tandem cycle double-effect absorption heat pump refers to that the solution cycle is tandem when the absorption heat pump realizes the double-effect process. So do single stage tandem triple effect.

Sixthly, in the recuperative single stage double-effect absorption heat pump, the first generator 1 and the second generator A2 all can be used as the high-pressure generator or low-pressure generator. They can be called as the high-pressure generator or low-pressure generator when it is necessary. Similarly, in the recuperative single stage triple effect absorption heat pump, the first generator 1, the second generator A3 and the third generator B3 all can be used as the low-pressure generator, medium voltage generator or low-pressure generator. They can be called as the high-pressure generator, medium voltage generator or low-pressure generator when it is necessary too.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Now combining the appended drawings and examples, we described the present invention in detail.

The solution tandem cycle recuperative generation-absorption system shown in FIG. 1 can be realized by the following way:

Firstly, structurally, it is mainly formed by the generator, the first absorber, the second absorber, the first solution heat exchanger, the second solution heat pump, the steam bleeding chamber, the first solution pump, the second solution pump and the third solution pump.

The generator 1 has the concentrated solution pipe which passes through the first solution pump 7, the first solution heat exchanger 4, the first absorber 2, and then connects the steam bleeding chamber 6. The steam bleeding chamber 6 has the concentrated solution pipe that passes through the second solution pump 8, the second solution heat exchanger 5 and then connects the second absorber 3. The second absorber 3 has the dilute solution pipe which passes through the second solution heat exchanger 5, the third solution pump 9 and then connects the first absorber 2. The first absorber 2 has the dilute solution pipe which passes through the first solution heat exchanger 4 and then connects the generator 1. The generator 1 has the residual heat medium pipe or thermal driving medium pipe which separately connects external. And the generator 1 also has the refrigerant vapor pipe which connects external. The first absorber 2 has the heated medium pipe and the refrigerant vapor pipe which separately connects external. The second absorber 3 has the refrigerant vapor channel and the heated medium pipe which separately connects external. The steam bleeding chamber has the refrigerant vapor pipe connected external.

Secondly, on the process, the residual heat medium or thermal driving medium heats up the dilute solution of the generator 1 and releases the refrigerant vapor. After that the concentrated solution of the generator 1 flows through the first solution pump 7, the first solution heat exchanger 4, the first absorber 2 and absorbs heat making parts of it vaporization, the concentrated solution enters the steam bleeding chamber and releases the refrigerant vapor. The concentrated solution of the steam bleeding chamber 6 flows through the second solution pump 8, the second solution heat exchanger 5 and then enters the second absorber 3 where it absorbs the refrigerant vapor coming from outside the system and releases heat to heated medium. The dilute solution of the second absorber 3 flows through the second solution heat exchanger 5, the third solution pump 9 and then enters the first absorber 2 where it absorbs the refrigerant vapor coming from outside the system and heats up the solution which flows through the first absorber 2 for meeting the heat demand of heated medium. The dilute solution pipe of the first absorber 2 flows through the first solution heat exchanger 4 and then reflows to generator 1 in which it is heated to release refrigerant vapor. Then we gain the solution tandem cycle recuperative generation-absorption system.

The solution tandem cycle recuperative generation-absorption system shown in FIG. 2 is similar to FIG. 1 in the structure and working principle. But there are two different aspects existing between the two. Firstly, the first absorber 2 has no heating medium pipe connected external. The solution of the first absorber 2 absorbs the refrigerant vapor and releases heat. And the heat is just used to heat the solution before vaporization. Secondly, there is no second solution pump 8 in FIG. 2.

The solution parallel cycle recuperative generation-absorption system shown in FIG. 3 can be realized by the following way:

Firstly, structurally, it is mainly formed by the generator, the first absorber, the second absorber, the first solution heat exchanger, the second solution heat pump, the steam bleeding chamber, the first solution pump and the second solution pump.

The generator 1 has the concentrated solution pipe which passes through the first solution pump 7, the first solution heat exchanger 4 and then connects the first absorber 2. The first absorber 2 has the dilute solution pipe which passes through the first solution heat exchanger 4 and then connects generator 1. The second absorber 3 has the dilute solution pipe which passes through the second solution heat exchanger 5, the first absorber 2 and then connects the steam bleeding chamber 6. The steam bleeding chamber 6 has the concentrated solution pipe that passes through the second solution pump 8, the second solution heat exchanger 5 and then connects the second absorber 3. The generator 1 has the residual heat medium pipe or thermal driving medium pipe which separately connects external. And the generator 1 also has the refrigerant vapor pipe which connects external. The first absorber 2 has the heated medium pipe and refrigerant vapor pipe which separately connects external. The second absorber 3 has refrigerant vapor channel and the heated medium pipe which separately connects external. The steam bleeding chamber has refrigerant vapor pipe connected external.

Secondly, on the process, the residual heat medium or thermal driving medium heats up the dilute solution of the generator 1 and releases the refrigerant vapor. The concentrated solution of the generator 1 flows through the first solution pump 7, the first solution heat exchanger 4, the first absorber 2 where it absorbs the refrigerant vapor coming from outside the system and heats up the solution which flows through the first absorber 2 for meeting the heat demand of heated medium. The dilute solution pipe of the first absorber 2 flows through the first solution heat exchanger 4 and then reflows to the generator 1. After that the solution which flows through the first absorber 2 absorbs heat making parts of it vaporization, the solution enters the steam bleeding chamber and releases refrigerant vapor. The concentrated solution of the steam bleeding chamber 6 flows through the second solution pump 8, the second solution heat exchanger 5 and then enters the second absorber 3 where it absorbs the refrigerant vapor coming from outside the system and releases heat to heated medium. The dilute solution of the second absorber 3 flows through the second solution heat exchanger 5, the first absorber 2 and absorbs heat making parts of it vaporization. Then the solution enters the steam bleeding chamber 6. Finally, we gain the solution parallel cycle recuperative generation-absorption system.

Compared with the solution tandem cycle recuperative generation-absorption system shown in FIG. 1, the solution parallel cycle recuperative generation-absorption system of FIG. 3 divides the solution into two parts with each independent circulating. The third solution pump 9 is removed in FIG. 3. However, they are both using the releasing heat to satisfy the absorption demand in another process. And the two both belong to the recuperative principle during the thermal cycle.

Seeing from the structure and working principle, the solution independent cycle recuperative generation-absorption system shown in FIG. 4 has no difference with FIG. 3 in essence. But the different between the two is as follows. The first absorber 2 has no heating medium pipe connected external. The solution of the first absorber 2 absorbs the refrigerant vapor and releases heat. And the heat is just used to heat the solution before vaporization.

The recuperative single-stage single-effect second-type absorption heat pump adopting the solution tandem cycle recuperative generation-absorption system shown in FIG. 5 can be realized by the following way:

Firstly, structurally, in the solution tandem cycle generation-absorption system shown in FIG. 1, we use the residual heat medium as the thermal driving medium of the generator 1 and add the condenser A1, evaporator B1, liquid refrigerant pump C1 in the system.

The generator 1 has the refrigerant vapor channel connected external can be considered as that generator 1 has refrigerant vapor channel connected condenser A1. That the steam bleeding chamber 6 has refrigerant vapor channel connected external can be considered as that the steam bleeding chamber 6 has refrigerant vapor channel connected condenser A1. That the first absorber 2 has refrigerant vapor channel connected external can be considered as that evaporator B1 has refrigerant vapor channel connected the first absorber 2. That the second absorber 3 has refrigerant vapor channel connected external can be considered as that evaporator B1 has refrigerant vapor channel connected the second absorber 3. Condenser A1 has liquid refrigerant pipe which passes through liquid refrigerant pump C1 and then connects evaporator B1. Condenser A1 has the cooling medium pipe connected external. Evaporator B1 has the residual heat medium pipe connected external.

Secondly, on the process, the residual heat medium heats up the dilute solution of generator 1 and releases refrigerant vapor provided to condenser A1. The refrigerant vapor released by the steam bleeding chamber is provided to condenser A1. The refrigerant vapor which enters condenser A1 releases heat to the cooling medium becoming liquid refrigerant. The liquid refrigerant of condenser A1 flows through liquid refrigerant pump C1 and then enters evaporator B1. The liquid refrigerant of evaporator B1 is heated by residual heat medium becoming refrigerant vapor. Evaporator B1 separately provides refrigerant vapor to the first absorber 2 and the second absorber 3. The heat release of the first absorber 2 is used to meet the heat demand of heated medium and satisfy the heating demand before the vaporization of solution. The heat release of the second absorber 3 is used to meet the (high temperature) heat demand of heated medium. Finally, we get recuperative single-stage single-effect second-type absorption heat pump.

The recuperative single-stage single-effect second-type absorption heat pump adopting the solution tandem cycle recuperative generation-absorption system shown in FIG. 6 can be realized by the following way:

Firstly, structurally, in the solution tandem cycle generation-absorption system shown in FIG. 2, we use the residual heat medium as the thermal driving medium of generator 1 and add condenser A1, the first evaporator B1, liquid refrigerant pump C1, the second evaporator D1, throttle E1 in the system.

That the steam bleeding chamber 6 has refrigerant vapor channel connected external can be considered as that the steam bleeding chamber 6 has refrigerant vapor channel connected condenser A1. That the first absorber 2 has refrigerant vapor channel connected external can be considered as that the first evaporator B1 has refrigerant vapor channel connected the first absorber 2. That the second absorber 3 has refrigerant vapor channel connected external can be considered as that the first evaporator B1 has refrigerant vapor channel connected the second absorber 3. Condenser A1 has liquid refrigerant pipe which passes through liquid refrigerant pump C1 and then connects the first evaporator B1. The first evaporator B1 has liquid refrigerant pipe which passes through throttle E1 and then connects the second evaporator D1. Condenser A1 has the cooling medium pipe connected external. The first evaporator B1 and the second evaporator D1 have the residual heat medium pipe which separately connects external.

Secondly, on the process, the residual heat medium heats up the dilute solution of generator 1 and releases refrigerant vapor provided to condenser A1. The refrigerant vapor released by the steam bleeding chamber 6 is provided to condenser A1. The refrigerant vapor which enters condenser A1 releases heat to the cooling medium becoming liquid refrigerant. The liquid refrigerant of condenser A1 flows through liquid refrigerant pump C1 and then enters the first evaporator B1. One part of liquid refrigerant in the first evaporator B1 absorbs residual heat medium becoming refrigerant vapor while another part of liquid refrigerant flows through throttle E1 and then enters the second evaporator D1. Residual heat medium heats up the liquid refrigerant of the second evaporator D1 becoming refrigerant vapor which is provided to the second absorber 3. The heat release of the first absorber 2 is used to meet the heat demand of heated medium and satisfy the heating demand before the vaporization of solution. The heat release of the second absorber 3 is used to meet the (high temperature) heat demand of heated medium. Finally, we get recuperative single-stage single-effect second-type absorption heat pump.

Compared with FIG. 7 and FIG. 6, the only difference between the two is adopting different recuperative generation-absorption systems.

Similarly, compared with FIG. 8 and FIG. 5, the only difference between the two is adopting different recuperative generation-absorption systems.

The recuperative single generator two-stage second-type absorption heat pump adopting the solution tandem cycle recuperative generation-absorption system shown in FIG. 9 can be realized by the following way:

The refrigerant vapor released by the steam bleeding chamber 6 is provided to condenser A2. The refrigerant vapor which enters condenser A2 releases heat to the cooling medium becoming liquid refrigerant. After that the pressure of liquid refrigerant from condenser A2 is promoted by liquid refrigerant pump D2, one part of the liquid refrigerant flows through throttle E2 and then enters evaporator B2 in which it absorbs residual heat vaporization. And another part flows directly through absorption-evaporator C2 vaporization. The refrigerant vapor produced by evaporator B2 is provided to absorption-evaporator C2. The refrigerant vapor produced by absorption-evaporator C2 is separately provided to the first absorber 2 and the second absorber 3.

The dilute solution of the first absorber 2 flows through the third solution heat exchanger F2 and then enters absorption-evaporator C2 in which it absorbs refrigerant vapor coming from evaporator B2 and heats up liquid refrigerant which flows through absorption-evaporator C2. The liquid refrigerant becomes refrigerant vapor. The dilute solution of absorption-evaporator C2 flows through the first solution heat exchanger 4 and then enters generator 1. The heat release of the first absorber 2 is used to meet the heat demand of heated medium and satisfy the heating demand before the vaporization of solution. The heat release of the second absorber 3 is used to meet the (high temperature) heat demand of heated medium.
